A Carnot engine is operated as an air conditioner to cool a house down in the summer. The air conditioning removes 14kj of the heat per second from the house, and maintain the inside temperature at 293k, while the outside temperature is 369k. The power required for the air conditioner under these operating conditions, in SI units, is closest to:

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
